During the siege of Jerusalem back in 1917, the British, in an effort to capture the city from an entrenched Ottoman garrison, started to airdrop “special” cigarettes. These “special” cigarettes were smoked by the Ottomans, but what they didn’t know is that they were filled with large doses of Opium!
Ottomans were too stoned to fight, so when they were doing their last stand at Sheria, the British were able to attack them and destroy their defense since the Ottomans were too high to mount a successful attack and defense. The British successfully took Sheria, and soon after Jerusalem!
In simpler words: The British strategy worked perfectly! The Ottomans didn’t even stop to check if the cigarettes contained anything, so by triggering their cigarette addiction, the British were able to celebrate Christmas at Jerusalem.
So next time an enemy offers you a cigarrete you might want to check the cigarette first.
